There are many forms of stamping molds, which can generally be classified according to the following main characteristics:
1. Classification based on process properties
(1) A die that separates materials along a closed or open contour line. Such as material cutting die, punching die, cutting die, cutting die, edge cutting die, cutting die, etc.
(2) A bending die is a mold that causes the blank or other blank to bend and deform along a straight line (bending curve), thereby obtaining a workpiece with a certain angle and shape.
(3) A deep drawing die is a mold that turns a blank sheet into an open hollow part, or further changes the shape and size of the hollow part.
(4) A forming die is a mold that directly replicates a rough or semi-finished workpiece into a convex or concave shape according to the drawing, while the material itself only produces local plastic deformation. Such as bulging molds, necking molds, expanding molds, undulating forming molds, flanging molds, shaping molds, etc.
2. Classification based on the degree of process combination
(1) A single process mold is a mold that completes only one stamping process in one stroke of a press.
(2) A composite mold has only one workstation, and in one stroke of the press, it is a mold that completes two or more stamping processes simultaneously on the same workstation.
(3) Progressive die (also known as continuous die) has two or more workstations in the direction of raw material feeding. It is a mold that completes two or more stamping processes on different workstations in one stroke of the press.
